Abstract

Introduction: Previous research on voice in Parkinson's disease (PD) has consistently demonstrated alterations in acoustic parameters, including fundamental frequency (F0), maximum phonation time, Shimmer, and Jitter. However, investigations into acoustic parameter alterations in individuals with PD are limited.

Methods: We conducted an experimental study involving 20 PD patients (six women and fourteen men). Subjective measures of voice (VHI-30 scale and GRBAS) and objective measures using the OnlineLAB App tool for analyzing biomechanical correlates of voice were recorded. The app analyzed a total of 22 biomechanical parameters of voice.

Results: The results of subjective measures were consistent with findings from previous studies. However, the results of objective measures did not align with studies that employed acoustic measures.

Conclusions: The biomechanical analysis revealed alterations in various parameters according to gender. These findings open up a new avenue of research in voice analysis for patients with PD, whether through acoustic or biomechanical analysis, aiming to determine whether the observed changes in these patients' voices are attributable to age or disease progression. This line of investigation will help elucidate the relative contribution of these factors to vocal alterations in PD patients and provide a more comprehensive understanding of the underlying mechanisms.

帕金森病患者嗓音的生物力学参数

前言以往对帕金森病（PD）患者嗓音的研究一致表明，患者的声学参数会发生变化，包括基频（F0）、最大发音时间、谛听（Shimmer）和抖动（Jitter）。然而，对帕金森病患者声学参数改变的研究还很有限：我们进行了一项涉及 20 名帕金森氏症患者（6 名女性和 14 名男性）的实验研究。我们记录了嗓音的主观测量结果（VHI-30 量表和 GRBAS），并使用 OnlineLAB App 工具进行了客观测量，以分析嗓音的生物力学相关性。该应用程序共分析了 22 个嗓音生物力学参数：结果：主观测量结果与之前的研究结果一致。然而，客观测量的结果与采用声学测量的研究结果并不一致：结论：生物力学分析表明，不同性别的嗓音参数会发生变化。这些发现为针对帕金森病患者的嗓音分析开辟了一条新的研究途径，无论是通过声学分析还是生物力学分析，其目的都是为了确定这些患者嗓音中观察到的变化是由年龄还是疾病进展引起的。这一研究方向将有助于阐明这些因素对帕金森氏症患者嗓音变化的相对影响，并提供对其潜在机制的更全面了解。
